BACKGROUND OF THE INVENTION

(a) Field of the invention

The invention discloses that the relay thermal conductor with better thermal conductivity coefficient and the interface thermal conductor having both or at least one of the specific heat capacity or thermal emissivity better than the relay thermal conductor are commonly integrated to form a prestressed clamping thermal conducting or heat dissipating structure having at least two layers in particular combination type thereby promoting the thermal conducting effect and avoiding loosening or deformation of the multi-layer structure material due to different coefficients of thermal expansion to result in poor thermal conducting surface unfavorable for thermal conduction.

(b) Description of the Prior Art

Except for the cooling or heating interior of heat pipe or other enclosed space having overall area for thermal conducting contacts, the cooling or heating source of the first thermal body of the conventional thermal conducting structure constituted by a single material is usually limited by the smaller thermally conducting area of the thermal conducting device, such as that if the heat source of first thermal body is the thermal energy of the heat loss in CPU of computer, power semiconductor or light emitting diode (LED), then if it is coupled with said thermal bodies or heat dissipating structural bodies for heat dissipating operation, if the thermal conducting or heat dissipating structure is made of single material, and even if the thermal conductivity coefficient of the single material is better, its specific heat capacity is usually not the best, such as that if the heat dissipater of CPU, power semiconductor, or light emitting diodes being made of copper material is heavier and expensive, and although it has a better thermal conductivity coefficient, its specific heat capacity and thermal emissivity is lower than aluminum;

If single material of better specific heat capacity and/or thermal emissivity with lighter weight and lower price is adopted, such as the heat dissipater being made of aluminum, though it has a higher specific heat capacity and thermal emissivity, its thermal conductivity coefficient is lower than copper material, therefore the thermal conducting effect for thermal conducting structure made of single material is more limited and it shall be further considered to avoid loosening or deformation of the multi-layer structure material due to different thermal conductivity coefficients to result in poor thermal conducting surface unfavorable for thermal conduction.

SUMMARY OF THE INVENTION

The invention innovatively discloses a thermal conducting principle and device for prestressed-clamping type multi-layered structure, wherein the multi-layered thermal conducting or heat dissipating structure is made of materials with different thermal characteristics and is different from the conventional thermal conducting or heat dissipating structure being made of single material, wherein for the thermal conducting principle and device for prestressed-clamping type multi-layered structure of present invention, the relay thermal conductor being made of material with better thermal conductivity coefficient is heat conductively coupled with the heating or cooling first thermal body at one end or surface thereof, and is coupled with the interface thermal conductor at the other end or surface thereof, and the interface thermal conductor having the thermal conducting characteristics with both or at least one of the 1) higher specific heat capacity relative to relay thermal conductor, or 2) better thermal emissivity to second thermal body relative to relay thermal conductor is used as the heat conducting carrier between relay thermal conductor and second thermal body, and is favorable for thermal energy conduction when there is temperature difference between first thermal body and second thermal body; in addition, the present invention further discloses that each structure layer being in prestressed-clamping type combined structure to reduce volume has the prestressed clearance (500) for producing clamping or outwardly expanding prestressing force to ensure good thermal conducting contact and avoid loosening or deformation of the multi-layer structure material due to different coefficients of thermal expansion to result in poor thermal conducting surface unfavorable for thermal conduction.
